Clean the scanner’s glass plate
You are recommended to clean the scanner's glass plate periodically, depending on how often you use the
scanner.
1. Turn off the printer using the Power key at the front, then also turn off the power switch at the rear and
disconnect the power cable.
2. There is a small lever at the rear left of the scanner. Slide the lever up and open the scanner cover.
WARNING! Do not lift the scanner while the scanner cover is open. Your fingers or hand may be
trapped or crushed.
